Manufacturing enterprises continue to grapple with transforming from their existing business model, which revolves around designing and selling tangible products, models centered on providing a blend of products services. Product-as-a-Service (PaaS) emerges as strategy capable catalyzing the shift toward higher levels circularity. However, effecting changes in operational methodologies value delivery mechanisms is imperative, consequently prompting modifications core strategies these...

Plastic industry is ubiquitous worldwide, and the generation of "plastic waste" has been steadily increasing to point being considered a high impact pollutant. The expanded polystyrene (EPS) plastic aware issue interested on trying recycling post-consumer material. Through recent study made in an alliance between private sector academy, feasibility EPS "mechanical" was proven; therefore, possible solution through circular economy model. aim present paper investigate potential environmental...

The analysis of the prime political ideologies that affect human behaviours and how these make people interact with their habitat is most necessary for policy making. objective present research to analyse relationship between an individual's ideology his/her environmental concern pro-environmental attitudes, last two influences on pro-electrical consumption attitudes. To achieve objective, we based information from surveys effectuated years apart. A total 3,395 household heads were...

The present study investigated citizens’ self-reported pro-environmental behaviors by adopting a survey and bootstrapping via structural equation modeling for five different personality traits. Adopting one traditional psycho-social theory, this investigates how motivations, values, intentions, norms, are connected using constructs from the value-belief-norm theory extended with external influences three behaviors, namely, waste preventer, green consumer, avoider, connections change between...

This study looks at pro-environmental behaviors (PEBs) for waste reduction in Ecuador's heavily populated Guayas area. The research, which focuses on green consumer, recycler, and waste-preventer behaviors, applying an Extended Theory of Planned Behavior (TPB) to investigate the influence attitudes, subjective norms, perceived behavioral control people's intentions behave environmentally uses external influences as moderating role variable. research intends contribute targeted treatments...

Plastic pollution of the natural environment is ubiquitous, and around 40% all plastic waste produced globally used in single-use products only 9% recycled. From this waste, expandable polystyrene pose a major problem because its great volume low density. To abord issue, authors proposed circular economy model for EPS post-consumer 2019 through case study with help one local manufacturer. Although idea promoting circularity seems priori to have good impact on environment, process...

A significant contributor to the waste stream is domestic single-use plastic used in households, being final disposal most cases local landfill. There a opportunity promote resource recovery and efficiency through introduction of circular economy strategies. However, knowledge management post-consumer country poor, there lack an efficient collection sorting system. In this context, spatial information on generation (DPWG) essential for recycling decision-making. The integration Geographic...

Systems for managing municipal solid waste are typically ineffective in developing nations because of governments' deficient financial and administrative frameworks, poor rules, a lack suitable infrastructure human resources. The informal sector plays an essential role these systems by reprocessing into secondary raw materials, reducing collection disposal costs, and, most importantly, benefiting the environment avoiding incineration landfilling. However, their actual contributions remain...

This study tackles the growing global concern about municipal waste management, particularly in cities like Grand Guayaquil Metropolitan Area (GGA). Through realistic field studies on situ household generation and geographic information system (GIS) tools, this work offers a framework to predict quantities types of recyclable for any metropolitan area Latin America. Over 4 weeks, students collected, sorted weighed types, including plastic, paper, metal, glass fabric, from 776 sampled GGA....

Transition towards a more sustainable society is complex task. The depletion of natural resources and waste generation cannot be sustained indefinitely, i.e. as increases, local landfills keep growing land availability reduces. introduction circular economy in effective household solid management practices should considered especially for third world countries, such Ecuador. In this context, plastic recycling an important step, particularly the case expanded polystyrene containers that...

Noise pollution is becoming a critical health risk for city life. In 2020, the COVID-19 pandemic forced many cities to implement several mobility restrictions. These restrictions changed human activity patterns and decreased noise levels that often affect urban settings. As number of infections decreased, so did outdoor activities, influencing population's perception noise. This paper aims evaluate changes in associated with between 2020 2021 Guayaquil, Ecuador. study used crowdsourcing help...

Ecuador is a country in which only third of the municipalities classify their waste before it collected by garbage collection services. The generates 4.06 million metric tons each year, constituted 62% organic, 25% recyclable and 13% are another type wastes. Of this total, 4% recycled, diminishing space for landfills increasing cost solid management. For reason, need urban recycling systems has become very important. A transfer station an important component management system functions as...

Currently, to achieve net-zero emissions, the transport sector is going through a decarbonization process, with Battery Electric Vehicles (BEVs) leading race. However, these vehicles present limited range and high charging time as barriers replacing 100% of sector. Also, BEVs cannot emissions given that electric rechargeable stations are powered by local grid electricity. Thus, even though do not produce greenhouse gas (GHG) directly; there indirect linked electricity used, relying on...

Vented lead-acid (VLA) batteries are still used for starting, lighting, and ignition in modern vehicles with internal combustion engines, even though this technology was developed the mid-19th century. Despite importance of VLA batteries, there is not a different End Life strategy besides recycling it. The present work aims to define methodology extending life span based on remanufacturing process, which includes assessing battery's performance before after reconditioning identifying...

Electricity demand has grown in almost 75% the last ten years, and with addition of 900 thousand new families from rural marginal areas to electricity grid, total may increase significantly. The understanding specific energy consumption patterns these sectors could explain influence on lead regional government policy promote their formal access. However, micro level analysis show different correlations among determinants than those usually reported previous macro models. data was taken a...

This paper estimated the domestic waste cooking oil (DWCO) generation for city of Guayaquil, Ecuador. The study also determined how social indicators influence quantity produced domestically by using Ordinary Least Square (OLS) regression. For this effect, a stratified random sampling methodology was used, resulting in selection 441 sample households study. Results show that produces 5.11 grams DWCO per capita every day also, with higher number youngsters between 12 and 18 years old produce...

A transition towards an economy able to decouple economic growth from resource throughput is needed. An answer this issue the circular since it pushes frontiers of sustainability by implementing value ecosystems in which products and materials are used as many times necessary. Circular business models such product lease pay-per-use also called product/service systems (PSS) or a service (PaaS) focus on selling performance instead products. The main objective paper gain more insights into...

Wastewater management (WWM) is an issue in low and middle-income countries' rural areas; the lack of technology funding have been identified as most critical. Marcelino Maridueña (MM) a village Ecuador that uses oxidation pond to treat its household wastewater. As result, organic load effluent varies depending on season volume treated. Also, it may generate emissions could harm environment. Therefore, hybrid system, i.e., activated sludge (conventional) coupled with algal photobioreactor...
